NASA's OSIRIS-REx spacecraft successfully performs a critical trajectory adjustment, preparing to deliver asteroid Bennu samples to Earth on September 24th.
he yellow diamonds indicate the dates of spacecraft maneuvers that slightly adjust its trajectory to get it closer, and then pointing at, and then above Earth.Post the trajectory adjustment, the spacecraft is now prepared to release the sample capsule at 8:42 am MDT / 10:42 am. EDT. The capsule will enter Earth's atmosphere at a strategically calculated speed and angle. It is expected to land 13 minutes post-release within a predetermined 36-mile by 8.5-mile area.
Ground teams will quickly transport the capsule via helicopter to a temporary clean room to avoid contamination. A recent rehearsal in Utah, involving the collection and helicopter transport of Earth rock samples, was described by NASA as their most realistic drill yet. During the recovery, the team will also collect nearby rock samples to assess potential contamination of the capsule.has more celestial journeys to embark upon.
OSIRIS-REx is about 4 million miles, or roughly 7 million kilometers, from Earth. It is hurdling through space at approximately 14,000 mph , all set for its historic rendezvous with Earth later this month.
